WASHBOARD.

SPECIFICATION forming part of Letters gPatentN 0. 741,950, dated October 29, 1903. Application filed May 18,1903. Serial No. 157,685. a. model.)

2 0 all whom it may concern:

Be it known that I,MEYER ZEMELMAN,a citif. zen of the United States, residing at Indian apolis, in the county of Marion and State of In};

diana, have invented certain new and useful Improvements in Washboards, of which the following is a specification.

This invention relates to frames for washboards, and has for its object a means for con structing the legs, back, and stay thereof of a single piece of material. p

The object consists, further, inra frame for washboards to receive a rubbing-plate, common to all washboards, which is removably secured in said frame.

The object consists, further, in a frame for washboards embodying many new and novel features over the old wooden frame, in which the principal ones are that the former will not shrink, warp, split, crack, or pull apart and is so arranged that the rubbing-plate may be replaced when it becomes worn, together with a suitable locking device for'securing the rubbing-plate therein. There are other features. The construction and arrangement of the several parts will be hereinafter more particularly described, and then pointed out in the claims. Referring to the accompanying drawings, which are made a part hereof and on which similar numerals of reference indicate similar parts, Figure 1 is a view, partly in elevation and partly in section, of my improved frame for washboards. Fig. 2 is a rear view. Fig; 3 is a sectional view on the line 3 3 in Fig. 1; Fig. 4 is a horizontal view on the dotted line 4 4 in Fig. 1. Figs. 5, 6, and 7 are detail views, on an enlarged scale, of a modified construction of the locking device for securing the rubbing-plate. I

In the drawings, 1 isthe frame, which is preferably composed of metal. The frame 1 has the side edges curled, which terminate in cylinders to form the sides 2. Formed in line with the body upon the sides thereof and having a portion thereof integral with the legs are the curved walls 3, which provide a semicircular recess and which, in conjunction with the semicircular stay or brace 4:, provide means for securing the rubbing-plate 5 to the body of the frame. The curved walls 3form a guide for the rubbing-plate 5, on which the linens are washed. The plate 5 isinserted between the curved walls 3 from the top, as will be readily understood by examining Fig. 3. A cross or rest plate 6 is provided with cylindrically-formed extensions 7, that telescope with and slide into the upper ends of the curved walls 3. These extensions 7 are cut so that'when placed into position the lower ends of the extensions will bear upon the upper edge of the rubbingplate 5, and thus serve to hold and lock said plate. Suitable catches S are secured within the extensions 7 and engage in any suitable manner with the curved walls 3, and it will be understood that when said extensions 7 are pressed down into the curved walls 3 the catches will lock the parts together, and thus firmly hold the rubbingplate in position. Hence it will be seen that I have an effective means for securing the rubbing-plate 5 when the latter is in position and which may be easily removed when worn and replaced by a new one. The frame 1 is .alsoprovided with a number of corrugationslO, which may extend in any desired direction and are intended to strengthen the same.

In Figs. 5, 6, and 7a modification of the locking device is shown, which is accomplished by forming the upper bar 12 in a semicircular manner, leaving'the ends thereof formed cylindrically where they engage with the curved walls 3, which provide the bearings for the bar. The bar 12 may be moved into the position shown in Fig. 6, in which position the rubbing-plate 5 may be removed from the frame. After said plate has been inserted, however, the bar 12 is turned as shown in Fig. 5, when the plate is locked.

Having thus fully described my said invention, what I desire to secure by Letters Patout is 1. In a Washboard, a frame and back made IOO being rolled to form a stay, in combination with a rubbing-plate engaging the slots and sides, and means for securing the rubbing plate in the frame.

2. In a washboard, a frame made of a single sheet of material, cut away centrally of its bottom, legs formed by the two projecting members, curved walls provided upon opposite faces of the body forming guides upon opposite sides thereof, and a rubbing-plate seat formed upon the lower edge of the body between the legs, in combination with a rubbing-plate adapted to fit upon the body thereof between the curved walls and have its lower edge rest upon the seat.

3. In a washboard, a frame made of a single sheet of material, cut away centrally of its bottom, legs provided by the two projecting members formed by the cut-away portion thereof, curved walls provided upon opposite faces of the body forming guides upon opposite sides thereof, and a rubbing-plate seat formed upon the lower edge of the body between the legs, in combination with a rubbing-plate adapted to fit upon the body there-' of between the curved walls and have its lower edge rest upon the seat, and a locking device having a semicircular formation removably mounted in the body and adapted to be moved either to allow the insertion of the rubbing-plate or to lock the same after the insertion into the frame.

4. In a washboard, a frame made from a single sheet of material and cut away upon its lower edge so as to form legs in line with the outer edges of the body thereof, and curved walls provided upon opposite edges of the body of the frame in line with the legs, in combination with a rubbing-plate adapted to be slidably mounted between said'curved walls, and a locking device adapted to telescope with the curved walls and rest on the I upper edge of the rubbing-plate for holding the rubbing-plate in position.

5. In a washboard, a frame made from a single sheet of material and cut away upon its lower edge so as to form legs in line with the outer edges of the body thereof, and curved walls upon opposite edges of the body of the frame in line with the legs, in combination with a rubbing-plate adapted to be slidably mounted between said curved walls, a locking device adapted to telescope with the curved walls and rest on the upper edge of the rubbing-plate for holding the rubbingplate in position, and a flexible means for engaging the curved walls, for the purpose set forth.

6. In a washboard, a frame made from a single sheet of material provided upon its lower edge with hollow legs 2, upon opposite sides thereof and in line with the legs, thecurved walls 3, and upon its lower edge between the legs with a curved stay 4, in combination with arubbing-plate slidably mounted between the curved walls and resting upon the stay.

7. In a washboard, a frame made from a single sheet of material having strengtheningstrips compressed from the body thereof and provided with hollow legs 2; upon opposite sides thereof and in line with the legs, the curved walls 3, and upon its lower edge between the legs with acurved stay 4, in combination with a rubbing-plate slidably mounted between the curved walls and resting upon the stay.

In witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this
